Good choice! From all the reviews it is the best cooled card out there! I have mine running rock solid @ 1200/1650 with 1.225v core and stock mem voltages. I was able to easily hit the CCC limit of 1100/1575 on stock voltage. My AISC is 68 percent. On air you can go to 1.3v and be safe so it looks like I have a lot of headroom to go up if I want, but it absolutely kills everything I throw at it and my temps never exceed 62C! Also it is dead silent. I can't hear it over my case fans which are pretty quiet. As for people having problems with drivers I have no issues what so ever. I used ATIman's uninstaller between my last card and this one and everything I have done works flawlessly. It seems that most of the people with problems either have CrossFire (imo is a stupid choice to get when the AMD drivers are still young for this series as they always have an atrocious amount of problems at the beginning) or I think they have no properly rid their system of old drivers or maybe run super cluttered systems.
Good luck as every card OCs differently, but you picked the best cooled one so your experience should be very nice.

Thank you so much for taking the time to respond to me. If it may, what is AISC? so it's possible i can do 1000-1050-ish @ stock volts?

Hey all,

I just placed an order for a XFX 7970. I have some concerns about coil whine -- seems like a lot, if not all, of people experience it. Does the 7950 experience coil whine?

If not, I may cancel and go for the 7950.

Since every card is different and I can't predict what your card will be able to pull on stock voltages, but I can tell you that my experience was that I was able to pull the sliders to the end (1100 core) and it was rock solid. Everyone gets different results though most reviews that I read stated that they needed more voltage to get to 1100 core and beyond, so maybe I got lucky.

AISC is some sort of computation the new GPU-Z does and it is thought that the higher the number the better the overclock as the chip leaks less voltage, but it was made with nVidia in mind so apparently the AMD numbers really don't tell us anything at the moment. I for one am proof of that as I have a low number and can overclock quite well. Just google AISC GPU-Z and I am sure you'll get better information as this is just what I have pieced together from a couple of posts and looking at GPU-Z myself.

All 79xx cards have it and I can tell you that mine has it pretty bad, but since I can't hear it while I am gaming unless I have my head in the case I am not worried about it at all. tongue.gif

I guess it could be an issue if you have an all silent water setup...

I just looked up OCCT. It looks like CPU and RAM O/C testing. Am I missing something?

I'm not sure how terrible coil whine will be, but I hope it will be unnoticeable.

Fears go unrecognised... smile.gif

Sold 6990, 7970 arrived today and for a $40 upgrade/sideways...I'm definitely happy. Less power consumption, less heat, 60fps constant on BF3.

However, I have not yet run anything with EyeFinity...which the 6990 handled without worries.

Happy so far smile.gif
